Purpose and body fitment

The presented glass has been designed specifically as an element for the rear right side zone, which ensures proper edge geometry, the correct bending radius, and compatibility with the Ford S-Max door guides and seals. This ensures the correct operation of the window lifting mechanism, water and noise tightness, and an aesthetic fit with the body line.

The AS3 tinted glass is a practical addition to the vehicle's factory configuration – it improves thermal comfort, reduces glare, and increases privacy for second-row passengers. At the same time, adequate light transmission is maintained, consistent with the nature of rear side windows.

Characteristics of AS3 tinted glass

Glass in the AS3 standard is a solution used in the rear zone of the vehicle, where comfort and interior protection are the priority. In practice, this means:

• reduced cabin heating during exposure to sunlight,
• reduced glare and improved visual comfort for passengers,
• a more toned-down, visually consistent appearance of the side of the body,
• better conditions for transporting luggage and items requiring less light exposure.

Thanks to the factory tint, there is no need to use additional films, which eliminates the risk of bubbles, peeling, or uneven surface shades.

Benefits of using original Ford glass

Choosing a window dedicated to the Ford S-Max from the Car windows group translates into a number of practical assembly and operational benefits:

• preservation of factory fit parameters for the door frame and seals,
• proper cooperation with the existing lifting mechanism and guides,
• visual consistency with the vehicle's other windows, including the rear left side,
• maintenance of the proper level of rigidity for the side door structure.

This is particularly important for post-accident repairs or replacing damaged glass, where dimensional repeatability and compliance with the manufacturer's original specification are key.

Condition of the item and use in service practice

The glass is a used item, which makes it an attractive cost-effective solution while maintaining the manufacturer's original specification. Such components are eagerly used in professional body and paint workshops and by conscious users who prefer parts from dismantling over replacements with uncertain parameters.

In practice, the installation involves transferring the glass to the existing door frame, using factory mounting points and guides. With a properly prepared door structure, this allows for the efficient restoration of full functionality of the side glazed zone.

If you are planning a comprehensive repair or upgrade of the side glazed zone in your Ford and need other elements from the same group, such as windshields, side windows, or rear windows, check the available parts in the Ford Car windows category.

More about selecting used body components

When choosing a used window, it is worth paying attention to the compliance of the glass markings, the type of tint, and the intended side of the vehicle. A good practice is to compare the parameters with the factory-installed element and use the vehicle manufacturer's markings.
